Specification of Letters Patent. I PatenteiJun 1920 Application filed September 4, 1919. serial 'No. 321,593.

To all whom it mag concern."

1 3e it known that I, Gnoncn T. EUARn,'a citizen of theUnited States, and a resident of Bradford, in the county of Stark and acter stated, which is especially adapted for use in connection with the valves of internal combustion engines, such as employed on automobiles in general use, but may of course be adapted for various other valves.

A further object is to provide improved means for lifting the pressure disk on the valve stem against the action of the valve spring and maintain the disk at approximate right angles to the stem so as not to exert any angular or torsional strain on the parts.

I-Ieretofore, various forms of valve spring lifters have been employed, but due to the pivotal connection of the lever or movable member, the pressure disk is caused to assume an angular position in accordance with the angular position of the lever. With my improved device this objectionable feature is entirely overcome. a

A further object is to provide a device of the character stated, which will hold the pressure disk in any position of adjustment and yet allow a quick release, as occasion may require.

WVith these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fullyhereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a View in elevation illustrating my improvements; and V Fig. 2 is a top plan view of the device detached.

1 represents an engine cylinder, 2 a valve stem, 3 a pressure disk'on the valve stem and 1 a coiled spring around the stem exerting downward pressure on the disk. This is common valve construction and forms no part of the present invention.

My improved valve spring lifter has a bar 5 which is made with a longitudinal slot 6 in its upper portion andatits lower end has an opening 7 receivingan eye 8 of: a hook 9 fi xed bar of the engine cylinder l. V

A normally horizontal-liftingarm 10 is provided with a forked'end ll'adapted to' straddle the'rod'2 and engage the under face of the disk'3. This lifting arm 10 is connected by a linklfl with the shorter endof an operating lever 12; The lever-12 is pivotally supported. on the bar 5 by means of a rivet 13, and rivets 15 and 16 respectively connect the ends of the link .14 with the arm 10 andlever 12. v

' A diagonal link 17 is pivotally connected at one end by means of the rivets 16 and at its other end is connected by a rivet 18 which extends through the arm 10 and is movable .in the slot '6 of bar 5. The arm 10 has a latcated in Fig. 1 and the longer end of lever 12 is forced downwardly, by reason of the links 14 and 17, the arm 10 will be elevated and maintained in a normally horizontal position. By reason of the frictional engagement of the rivets with the several parts and the diagonal strain imparted by the link 17,

the arm 10 will hold the disk 3 in any position to which it is adjusted so that it is not necessary to maintain a pressure on the lever 12 for this purpose. When, however, it is, desired to release the disk, a slight pressure on the finger 19 will overcome the binding action of the parts and the disk can be permitted to lower.

Various slight changes may be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise detailsset forth but consider myself at liberty to make such changes. and alterations as fairly fall within the spirit. and scope of the appended claims.

I claim: v

1. A valve spring lifter, comprising a bar, a lifting arm, a lever pivotally connected to the bar, a link connecting the arm and the the saidhook adapted to eng'ageover a V and the first-mentioned link, and at its other a lever pivotally connected to the bar, a link connecting the lever and the arm, and a diagonally positioned link connected at one end to the pivotal connection of the lever end connected to the arm at its point of movable connection With'the bar.

3. A valve spring lifter, comprising a bar, a lifting arm, a lever pivotally connected to ..the bar, a link connecting the arm and the lever, and asecond link connected to the lever and to-the arm and movably connected to the bar, said arm having a forked end and a laterally; projecting-finger on the otherend of sand arm. I

' 4. A valve sprin lifter, comprising a bar, a lifting arm mova ly connected to the bai, a lever pivotally connected to the bar, a link connecting the lever and the arm, and a end to the pivotal connection of the lever and the first-mentioned link, and atits other 7 end connected to the arm at its point of movable connection Wltll'tllB bar,1said arm having a forked end and a laterally projecting finger on the other end of said arm.

5. A valve spring lifter, comprising a bar having a longitudinal slot therein, a hook on'the lower endof the bar adapted to engage a fixed support, an arm normally at right angles to the bar, a lever pivotally connected tothe bar, a normally vertical link connecting the arm and the lever, a diagonal link connected at one endto the pivotal con-' the other end of said diagonal link with the arm and movable in the slot of the bar.
